Answer:

Step-by-step explanation:

C - B < A < C + B

25 - 7 < A < 25 + 7

18 < A < 32

A can have any length between 10 and 32.

In case it's a right angle triangle,

A² = 25² - 7²

A² = 576

A = 24

Answer:

A 24

Step-by-step explanation:

Assuming this is a right triangle, we can use the Pythagorean theorem

a^2+ b^2 = c^2

a^2 + 7^2 = 25^2

a^2 +49= 625

Subtract 49 from each side

a^2 +49-49 = 625-29

a^2 = 576

Take the square root of each side

sqrt(a^2) = sqrt(576)

a = 24

We roll a pair dice 10,000 times. Estimate the probability that the number of times we get snake eyes (two ones) is between 280

Natali5045456 [20]

Answer:

0.3573 = 35.7%

Step-by-step explanation:

We roll a pair of dice 10,000 times so the mean and standard deviation is,

μ = 10000/36 =277.7 σ = $\sqrt{10000*\frac{35}{36^{2} } } =16.4$

$z_{1}$ = (280 - 277.7)/16.4 = .14

$z_{2}$ = (300 - 277.7)/16.4 = 1.35

Probablity (range)

0.3573

Z(low)=0.14 0.555766357

Z(upper)=1.36 0.91304644

(07.05)<br> Graph the first six terms of a sequence where a = -10 and d = 3.

butalik [34]

Answer:

Step-by-step explanation:

Using the formular, Sn = n/2(2a + (n - 1)d)

where, n = 6: Sn = 6/2( -20 + 5(3)) = 3(15 - 20)

∴ Sn = 15
